In the single-opening motorized window shade shown in fig. 1, the window shade material 2 is pulled out from one end portion of the window shade rail 1 toward the other end portion, or the window shade material 2 is folded from the other end portion of the window shade rail 1 toward the one end portion.
A guide pulley 3 is movably supported on the curtain rail 1, and a plurality of pulleys 4 are movably supported between the guide pulley 3 and the right end of the curtain rail 1. Further, the blind material 2 is suspended and supported on the guide pulley 3 and the pulley 4.
Conveyor devices 5 and 7 are attached to both left and right ends of the curtain rail 1, and an endless conveyor belt (not shown) that moves in the curtain rail 1 is hung on the conveyor devices 5 and 7. Further, a motor unit 6 is suspended and supported on the conveyor 5 at the right end side of the curtain rail 1, and the conveyor belt is moved in the curtain rail 1 by the driving force of a motor 35 disposed in the motor unit 6.
Then, the guide pulley 3 moves from one end portion of the curtain rail 1 toward the other end portion or from the other end portion of the curtain rail 1 toward the one end portion by the forward or reverse rotation of the motor 35.
(constitution of Motor Unit)
Next, the structure of the motor unit 6 mounted on the conveying device 5 will be described. Fig. 2 is a sectional view of a motor unit housing a control device according to an embodiment of the present invention.
As shown in fig. 2, the motor unit 6 includes a motor 35, an electromagnetic clutch 34, an optical sensor 31 constituting a rotation detector, a sensor substrate 32, a slit plate (slit board)33, a controller 36, a switch circuit board 37, a modular circuit board (module) 38, a power supply circuit board 39, and the like, which are housed in a substantially square tubular motor case 61.
The switch circuit board 37 is used when any one of a plurality of control modes preset for conveying the window covering material 2 is set. The switch circuit board 37 is connected to the control unit 36 by a predetermined wiring, and the switch circuit board 37 is attached to a unit cover 63, and the unit cover 63 is attached to the lower end of the motor case 61.
The modular circuit board 38 has a cable input for connecting an external operating switch (not shown). By operating the operation switch, various operations (for example, the rotation speed of the rotating shaft of the motor 35 corresponding to the target speed set as the target speed by the motor drive of the normal motorized window shade) can be set in the control unit 366 mounted on the control device 36. The operation switch may be configured as: a means for setting the control device 36 by wire or setting the control device 36 by wireless remote operation.
The power supply circuit board 39 is composed of a power supply circuit that receives ac power from the outside via a cable 41 and converts the ac power into dc power, and supplies power to each functional unit.
The switch circuit board 37, the modular circuit board 38, the power supply circuit board 39, and the control device 36 are mounted on the rack, respectively.
The rotation shaft of the motor 35 is connectable to a rotation output shaft 42 of the motor unit 6 (i.e., the rotation shaft of the slit plate 33 of the rotation detector) via the electromagnetic clutch 34, and the rotation output shaft 42 protrudes upward from the base member 62. The rotation output shaft 42 is attached to a pulley (not shown) that meshes with the endless belt so as to rotate. Therefore, the belt for conveyance moves in the curtain rail 1 in accordance with the rotation of the pulley, and the endless belt for conveyance and the pulley function as a rotation transmission mechanism with respect to the rotation output shaft 42.
(constitution of control device)
Next, the configuration and operation of the motor 35, the electromagnetic clutch 34, the rotation detector (the optical sensor 31, the sensor substrate 32, and the slit plate 33), and the control device 36 will be described. Fig. 3 is a diagram showing a configuration example of the control device 36 according to an embodiment of the present invention.
As shown in fig. 3, the motor 35, the electromagnetic clutch 34, and the rotation detector (the optical sensor 31, the sensor substrate 32, and the slit plate 33) are connected to a control device 36. The rotation detector is composed of a slit plate 33 attached to the output side rotating shaft of the electromagnetic clutch 34 and an optical sensor 31 provided on the sensor substrate 32, and can capture a light beam passing through the rotating slit plate 33 as a pulse signal. Therefore, the presence or absence of rotation, the rotation direction, and the rotation speed of the rotary output shaft 42 can be detected by the rotation detector, and the drive distance, the drive speed, the continuous external force, and the like of the endless belt can be detected.
The control device 36 includes: a wired setting signal input unit 361, a remote setting signal input unit 362, a motor drive control unit 363, a clutch drive control unit 364, a rotation detection signal input unit 365, and a control unit 366.
The wired setting signal input unit 361 inputs signals for specifying various operations (for example, the rotation speed of the rotary shaft of the motor 35 corresponding to the target speed) to the control unit 366 via the operation switches connected to the module circuit board 38 by a wire, and sets the signals in the control unit 366.
The remote setting signal input unit 362 inputs signals for specifying various operations (for example, the rotation speed of the rotary shaft of the motor 35 corresponding to the target speed) to the control unit 366 by wireless remote operation via the operation switches connected to the module board 38, and sets the signals in the control unit 366.
The motor drive controller 363 controls the rotation of the motor 35 in accordance with a control instruction from the controller 366.
The clutch drive control section 364 controls the driving of the electromagnetic clutch 34 in accordance with a control instruction from the control section 366, wherein the electromagnetic clutch 34 connects or disconnects the rotary output shaft 42 to or from the rotary shaft of the electric motor 35.
The rotation detection signal input unit 365 receives a signal of the rotation detector (the optical sensor 31, the sensor substrate 32, and the slit plate 33) provided on the rotation output shaft 42, and outputs the signal to the control unit 366 as a pulse signal.
The control unit 366 controls the operations of the clutch drive control unit 364 and the motor drive control unit 363 based on the signal from the rotation detection signal input unit 365.
Next, an example of the control unit 366 of the control device 36 will be described with reference to fig. 4. Fig. 4 is a block diagram showing an example of the control unit 366 of the control device 36 according to the embodiment of the present invention.
The rotation direction monitoring unit 3661 monitors the presence or absence of rotation of the rotation output shaft 42 based on the pulse signal from the rotation detection signal input unit 365, and transmits the pulse signal to the rotation direction detecting unit 3662 when the rotation output shaft 42 is rotated based on the opening and closing operation of the window blind by the hand-pulling operation.
The rotation direction detecting unit 3662 determines the rotation direction of the rotation output shaft 42 from the pulse signal related to the rotation of the rotation output shaft 42 acquired via the rotation direction monitoring unit 3661, notifies the drive control unit 3665 of the rotation direction, and transmits the pulse signal related to the rotation of the rotation output shaft 42 to the rotation speed monitoring unit 3663.
Rotation speed monitoring unit 3663 monitors the rotation speed of rotation output shaft 42 (i.e., the rotation speed corresponding to the pull-in speed) based on the pulse signal relating to the rotation of rotation output shaft 42, compares the monitored rotation speed with a predetermined set target rotation speed (i.e., a target speed compared with the pull-in speed), and notifies clutch connection control unit 3664 of the fact when the rotation speed of rotation output shaft 42 changes from a state higher than the target rotation speed to the target rotation speed or less (i.e., when the pull-in speed changes from a state higher than the target speed to the target speed or less). In addition, when comparing the hand pulling speed with the target speed, the determination is made in consideration of the influence of the speed deviation (jitter). When the hand pulling speed is maintained below the target speed from the beginning, the hand pulling motion is maintained. Here, the "target speed" may be a speed set as a target by driving a motor of a general motorized window treatment, for example.
Clutch connection control unit 3664 outputs a control instruction to clutch drive control unit 364 to connect rotation output shaft 42 to the rotation shaft of motor 35, based on a notification that the rotation speed of rotation output shaft 42 is equal to or less than the target rotation speed (i.e., a notification that the pull-in speed is equal to or less than the target speed), and also notifies drive control unit 3665.
When receiving a notification of the rotation direction of the rotation output shaft 42 from the rotation direction detection unit 3662 in a state where the rotation output shaft 42 is separated from the rotation shaft of the motor 35, the drive control unit 3665 outputs a control instruction to the motor drive control unit 363 to rotationally drive the output shaft 42 at the initial rotational speed in the rotational direction, wherein the initial rotation speed of the rotary output shaft 42 corresponds to a predetermined initial driving speed related to the opening and closing of the curtain, when a notification that the connection of the rotation output shaft 42 to the rotation shaft of the motor 35 is completed is received from the clutch connection control portion 3664, the drive control unit 3665 outputs a control instruction to the motor drive control unit 363 to rotationally drive the window shade in the rotational direction at a rotational speed corresponding to a drive speed predetermined as a normal operation state of the window shade.
Further, the motor drive control unit 363 preferably: the motor 35 is driven to reduce the speed from the initial driving speed to a driving speed predetermined as a normal operation state of the window covering.
Here, the following operation is performed for control when the window curtain is transitioned from the open/close operation state (normal operation state) of the window curtain by the motor drive to the state (standby state) in which the manual operation by the operator is not performed.
First, the following configuration can be formed: the rotation direction monitoring unit 3661 counts (count) the pulse signals related to the rotation of the rotation output shaft 42, and determines where the guide pulley 3 is located on the curtain rail 1. Further, the following configuration can be formed: the position of the guide pulley 3 on the curtain rail 1 is calibrated (corrected) at any time (for example, at the time of installation of the device or periodically), and the position of the guide pulley 3 on the curtain rail 1 is grasped from the count value of the pulse signal and notified to the drive control unit 3665.
Further, the following configuration can be formed: the motor drive control unit 363 has a function of detecting an overload state for forcibly stopping the motor 35, forcibly stops the motor 35 in the overload state, and notifies the drive control unit 3665 of the control unit 366 of the overload state. For example, when the motor 35 is operated by feedback control driven by a constant voltage, a motor drive current indicating an overload state flows when the position of the guide pulley 3 reaches the end portion on the curtain rail 1 or when the curtain movement is forcibly stopped by the operator (i.e., the rotation of the rotary output shaft 42 is stopped). Therefore, the overload state can be detected by detecting and monitoring the motor drive current.
Therefore, the following configuration can be formed: when the position of the guide pulley 3 moves to the vicinity of the end portion of the curtain rail 1 during driving of the motor 35 or when receiving information notification for forcibly stopping the overload state of the motor 35, the drive control unit 3665 gives the following control instructions to the motor drive control unit 363 and the clutch drive control unit 364: the rotation of the motor 35 is stopped and the electromagnetic clutch 34 is disconnected.
Alternatively, the following configuration can be formed: the drive control unit 3665 is configured to receive notification of stop of rotation of the slit plate 33 (i.e., stop of rotation of the rotary output shaft 42) from the rotation direction monitoring unit 3361, and to give control instructions to the motor drive control unit 363 and the clutch drive control unit 364 when the rotation of the rotary output shaft 42 is stopped, as follows: the rotation of the motor 35 is stopped and the electromagnetic clutch 34 is disconnected.
The function of the control unit 366 of the present example can be configured by a computer. A program for causing the computer to realize the functions of the control section 366 is stored in a memory provided inside or outside the computer. A program describing the processing contents for realizing the functions of the control unit 366 can be appropriately read from the memory under the control of a Central Processing Unit (CPU) or the like provided in the computer, and the computer can realize the processing corresponding to the functions of the control unit 366. Further, a part of the functions of the control unit 366 illustrated in fig. 4 may be realized by hardware, and the rest may be configured by a computer.
Hereinafter, a processing example when the function of the control unit 366 is configured by a computer will be described with reference to fig. 5. Fig. 5 is a flowchart showing an example of the operation of the control unit 366 of the control device 36 according to the embodiment of the present invention. Here, control when a window curtain is moved from a state in which a manual operation by an operator is not performed (standby state) to a state in which the window curtain is opened and closed by driving of a motor (normal operation state) will be mainly described.
(operation of control section)
When the operator is not pulling (in the standby state) (step S1), the control unit 366 monitors whether or not the rotation output shaft 42 is rotating based on the curtain opening/closing operation by the pulling operation, based on the pulse signal from the rotation detection signal input unit 365 (step S2). This enables detection of a hand-pulling operation.
When the rotation output shaft 42 is not rotated (no in step S2), the control unit 366 monitors until rotation of the rotation output shaft 42 occurs, and calculates a hand-pulling direction (that is, a rotation direction corresponding to the rotation output shaft 42) when a hand-pulling operation is present, that is, when rotation of the rotation output shaft 42 is present in a state where the rotation output shaft 42 and the rotation shaft of the motor 35 are separated (yes in step S2) (step S3).
Next, the controller 366 controls the motor drive controller 363 to: the rotation of the motor 35 is started by performing the rotational driving in the rotational direction of the rotational output shaft 42 corresponding to the pull direction at the initial rotational speed of the rotational output shaft 42 corresponding to the predetermined initial driving speed related to the opening and closing of the window covering (step S4).
Further, the control unit 366 calculates the pull-up speed, that is, the rotation speed of the rotation output shaft 42 in a state where the rotation output shaft 42 and the rotation shaft of the motor 35 are separated from each other (step S5).
Next, the control unit 366 monitors whether the pulling speed has changed from a state higher than the target speed to the target speed or less, that is, whether the rotational speed of the rotary output shaft 42 has changed from a state higher than the target rotational speed to the target rotational speed or less (step S6), and when the pulling speed is maintained at a state higher than the target speed (step S6: "yes"), the monitoring is continued until the pulling speed has changed to the target speed or less. On the other hand, when the pull-up speed is equal to or lower than the target speed (step S6: no), the control unit 366 outputs the following control instruction to the clutch drive control unit 364: the rotation output shaft 42 is connected to the rotation shaft of the motor 35 (step S7).
After the electromagnetic clutch 34 is connected, the controller 366 outputs the following control instructions to the motor drive controller 363: the curtain is rotationally driven in the rotational direction at a rotational speed corresponding to a drive speed predetermined as a normal operation state of the curtain (step S8).
Finally, as described above, when the position of the guide pulley 3 is moved to the vicinity of the end portion of the curtain rail 1 during the driving of the motor 35, or when the information notification for forcibly stopping the overload state of the motor 35 is received, or when the stop of the rotation of the slit plate 33 (i.e., the stop of the rotation output shaft 42) is detected, the control unit 366 instructs the motor drive control unit 363 and the clutch drive control unit 364 to control: the rotation of the motor 35 is stopped and the electromagnetic clutch 34 is disconnected (step S9).
As described above, according to the control device 36 and the program thereof of the present embodiment, the following motorized window shades can be realized: that is, smooth opening and closing of the curtain can be performed by speed control in consideration of the hand-pulling speed of the operator without causing the operator to feel uncomfortable.
Further, as long as the motorized window shade uses the control device 36 and the program thereof according to the present embodiment, in the opening/closing operation state (normal operation state) of the window shade by the motor drive, the rotation direction and the rotation speed of the motor 35 are controlled in accordance with the pull-in direction and the pull-in speed, and therefore, the window shade can be opened or closed at a desired drive speed suitable for the operator.
Further, as long as the motorized window shade uses the control device 36 and the program thereof according to the present embodiment, the rotation output shaft 42 and the rotation shaft of the motor 35 are separated and disconnected by the electromagnetic clutch 34 in the standby state, and thus the window shade can be opened or closed by a manual operation. That is, when the operator performs the pulling operation, the control device 36 detects the start of rotation and the direction of rotation of the pulling operation based on the signal from the rotation detector (the optical sensor 31, the sensor substrate 32, and the slit plate 33), and starts the rotation of the motor 35 in the direction of rotation corresponding to the direction of pulling, and at this time, the rotation output shaft 42 and the rotation shaft of the motor 35 are still in the off state by the electromagnetic clutch 34, and therefore, the pulling operation is not affected at all.
Further, as long as the motorized window treatment using the control device 36 and the program thereof according to the present embodiment compares the pull-in speed calculated from the signals from the rotation detector (the optical sensor 31, the sensor substrate 32, and the slit plate 33) with a settable target speed (for example, a speed set as a target by motor driving of a normal motorized window treatment), and continues monitoring the pull-in speed when the pull-in speed is relatively high, and continues this state while the operator continues operating at a speed higher than the target speed, the operation intended by the operator is not hindered.
Further, as long as the motorized window shade uses the control device 36 and the program thereof according to the present embodiment, when the pull-in speed decreases due to release or the like after the pull-in operation by the operator and becomes equal to or lower than the target speed, the rotational output shaft 42 is connected to the rotation shaft of the motor 35 by the electromagnetic clutch 34, so that the speed control from the pull-in speed to the target speed can be smoothly performed. The drive speed in the normal operation state does not necessarily need to be equal to the target speed for transition to the normal operation state of the window covering, and the target speed may be used as a threshold for transition from the standby state to the normal operation state.
Further, as long as the motorized window treatment using the control device 36 and the program thereof according to the present embodiment is not driven by a motor based on a fixed time period after the external force is stopped as in the case of the technique of patent document 1, the speed control can be realized by appropriately detecting the pull speed that may vary according to the pull operation of the operator in accordance with the setting of the target speed, in consideration of the pull speed within the range of the operator's intention.
The present invention has been described above by way of examples of specific embodiments, but the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the technical spirit thereof. For example, although the single-opening motorized window treatment has been described as an example in the above embodiment, the present invention can be applied to other applications such as a double-opening motorized window treatment.
In addition, although the above embodiment describes an example in which the speed control is performed by the motor 35 by comparing the pull-in speed with the single target speed with respect to the operation of the control unit 366 of the control device 36, the following configuration may be adopted: for example, the target speed is separately determined, and the speed control is performed by the motor 35 depending on whether or not the hand-pulling speed is changed from a state higher than the first target speed to a state lower than the second target speed (first target speed > second target speed). The following configuration may be formed: for example, when the operator starts the hand-pulling operation at a speed equal to or lower than the first target speed to open or close the window covering, the hand-pulling operation by the operator is preferentially executed, and when the hand-pulling speed is equal to or lower than the second target speed (the first target speed > the second target speed) from a state in which the hand-pulling speed is higher than the first target speed, the speed control is performed by the motor 35. Thus, even when a large speed deviation occurs when detecting the pull-up speed, the influence of the speed deviation can be alleviated, and more stable drive control can be realized.
In addition, the following configuration can be formed: the control device 36 sets different target speeds in the opening direction and the closing direction of the window blind to the control unit 366 via the wired setting signal input unit 361 or the remote setting signal input unit 362. This can improve the convenience of the operator according to the application.
In addition, the following configuration can be formed: when the position of the guide pulley 3 moves to the vicinity of the end portion on the curtain rail 1 while the motor 35 is driven, the control device 36 controls the motor 35 to be stopped by deceleration when the control unit 366 stops driving the motor 35 from a normal operation state (for example, a driving state at a target speed). Thus, even in a series of operations from the pull-out operation to the continuation of the operation by the motor drive to the stop, a dynamic beauty can be created.
(availability in industry)
According to the present invention, since smooth curtain opening and closing operations can be performed by speed control in consideration of the hand-pulling speed of the operator, the present invention can be used in applications such as a motorized curtain.
